Structure and Dielectric Properties of (Sr,Ca)TiO_3 Ceramics
Source abstract
Abstract
The phase component, structure and dielectric properties of (Sr,Ca)TiO3 systems were studied. When ST/CT ratio is 7:3, a main crystalline phase (Sr0.7Ca0.3)TiO3 complete solid solution with the ABO3 perovskite structure is formed, the dielectric properties are improved by a microscale next crystalline phase BNT(Ba6Ti2Nb8O30) with the tungsten bronze structure in the system. The new ceramic materials with excellent dielectric properties (e(20℃IMHZ) 250, αc(-55-+125℃) = -1150ppm/℃, tgδ(20℃IMHZ) 5×10-4, ρv(20℃100VDC) 1013Ω·cm) do not contain lead or bismuth , and can be used for Q group multilayer ceramic capacitors.
